I lost the love of my life

And I wonder if I will find anyone else as sensitive and supportive as he was. He was very emotionally expressive when you got to know him. Those are other traits I look in a mate sensitive, empathetic, and emotionally tender and expressive. It’s all my fault I lost the love of my life and for the last two and half years he wants nothing to do with me which really hurts. He promised we would always be good friends but didn’t keep that promise after dating someone else and I broke my promise to always be his girlfriend and eventually fiancee and wife. Well he is happy now with his wife after I broke his heart. What can you do? I have to move on without him in my life but he will always remain in spirit and within the memories we made. He is in my thoughts, dreams, and memories of my heart.
